The present invention relates to a removable media device, a host device, a program, and a recording medium thereof, which are loaded with a medium such as a connected flash memory and used by connecting to a host device such as a PC (Personal Computer).

  In order to operate an application program (hereinafter referred to as “AP”) of a host device such as a PC, even a simple task requires a minimum knowledge about the PC, which is difficult for beginners. For example, when starting a specific AP, it is necessary to select one AP from a plurality of APs by operating a mouse or the like, and in some cases, it is also necessary to set an operating environment using a keyboard. .

For this reason, conventionally, a technique has been developed and proposed for automatically executing related APs triggered by media insertion without user intervention. Specifically, the removable medium includes a task / disk control file, and the task / disk control file stores all necessary configuration information for running the associated AP from the removable medium. The AP can be automatically executed based on the configuration information (see, for example, Patent Document 1).

<Operation of the device>
FIG. 5 is a flowchart showing the operation of the removable media device according to the embodiment of the present invention. The processing procedure of the media control program is also shown. It is assumed that the media control program is recorded in advance as firmware in an EEPROM (Electrically Erasable and Programmable Read Only Memory, not shown) built in the removable media device 10.
Hereinafter, the operation of the removable media device 10 will be described with reference to FIG. 5 (see FIG. 2 as appropriate).

In the removable media device 10, the media insertion detection unit 101 first detects that the removable media 11 has been inserted (Yes in S501), and activates the dedicated media recognition unit 102. The dedicated media recognition unit 102 refers to the identifier of the header area A of the inserted removable medium 11 (S502), and recognizes that it is a dedicated media for starting the AP (Yes in S503). Here, it is assumed that a predetermined mark is written as an identifier.
Assume that after the inserted removable medium 11 is recognized as a dedicated medium, the inquiry command receiving unit 103 receives an inquiry command from the host device 20 (Yes in S504). The inquiry command is a command for inquiring whether the AP activation flag of the removable medium 11 is on.

Then, the flag recognition unit 104 of the inquiry command response unit 100 refers to the header area A and returns an AP activation flag to the higher-level device 20 (S505). Subsequently, it is confirmed that the AP activation flag is set to ON (Yes in S506), the header information transfer unit 105 is activated, and the AP name, storage location, and AP execution contents set in the header area A are activated. Is transferred to the host device 20 (S507).
Furthermore, if the AP storage location is in the same removable medium 11 (Yes in S508), the AP is also transferred to the host device 20 (S509). The above is the operation of the firmware built in the removable media device 10.

  Next, FIG.6 and FIG.7 is a flowchart which shows operation | movement of the high-order apparatus based on embodiment of this invention. 6 shows the processing procedure of the monitoring utility prepared as the program according to the embodiment of the present invention, and FIG. 7 shows the processing procedure of the format utility prepared as the program according to the embodiment of the present invention. It shows.

The operation of the monitoring utility will be described with reference to FIG. 6 (see FIG. 3 as appropriate). In the host device 20, the inquiry command issuing unit 201 issues an inquiry command to the removable media device 10 when the predetermined time interval timed by the timer 207 is reached (Yes in S601) (S602). The removable media device 10 that has received this inquiry command returns a response referring to the header area A. The flag receiving unit 202 of the inquiry command response receiving unit 200 receives the AP activation flag (S603). When the AP activation flag is set to ON (Yes in S604), the header information receiving unit 203 receives the AP name, the storage location, and the AP execution content as header information (S605).
Here, when the storage location is the insertion medium (Yes in S606), the AP execution unit 204 reads and executes the AP stored in the removable medium 11 (S607). If the data is stored in another storage medium such as the AP storage unit 208 of the host device 20 (No in S606), the AP is read from the storage medium and executed (S608). As a result, the activation of the AP is automated, and detailed operation contents including input and the like are passed to the AP in accordance with the set “AP execution contents”, so that a normal mouse and keyboard operation is not required. .

When the AP is executed, if a result storage instruction is given as “AP execution contents” transferred from the header area A (Yes in S609), the AP execution unit 204 specifies the AP execution result according to the instruction. Save in place (S610).
Although not shown in the flowchart of FIG. 6, as will be described later, the AP execution unit 204 executes when the removal media 11 is ejected from the removal media device 10 and an ejection notification is received during AP execution. By interrupting the AP inside, data destruction due to media insertion mistakes is prevented. Details will be described later.

Next, the operation of the format utility will be described with reference to FIG. 7 (see FIG. 3 as appropriate).
First, in the host device 20, the format request receiving unit 205 receives a format request for the removable medium 11 (Yes in S701). As a result, the header information setting unit 206 is activated, and first, the header area A is allocated in the removable medium 11 (S702). Then, the input / output of data by the dialogue for generating header information is started with the user using the man-machine device 30 (S703).
That is, the header information setting unit 206 generates a screen and a message for prompting the user to input a dedicated media identifier, an AP activation flag, an AP name and a storage location, and AP execution contents. Further, the header information setting unit 206 takes in the data input by the user who viewed the screen and the message, and sets the fetched data in the header area A in a predetermined format.

Specifically, when the removable media 11 inserted into the removable media device 10 is formatted as a dedicated media (Yes in S704), the header information setting unit 206 generates identifier data (predetermined mark) (S705), Also, data for setting on / off of the AP activation flag in accordance with the user input is generated (S706, S707, S711). Then, the user input for the AP name and storage location is captured (S708), the user input for the AP execution content is captured (S709), and the content of the captured data input is set in the header area A (S710).
In S704, when the medium is not a dedicated medium (No in S704), the normal format is executed (S712).
After the above format processing is performed, the AP can be automatically executed only by a dedicated medium.

<Operation of application example>
FIG. 8 is an operation sequence diagram showing the operation of the application example according to the embodiment of the present invention. Specifically, the operation sequence is shown when the user ejects the dedicated medium and cancels the work by the AP.
Here, the flow of operations among the AP, the monitoring utility (MU), the media control program (FW), and the user (USER) is shown, and there is a case where data destruction is prevented by providing a scheduler function to the AP execution contents. Illustrated. A user (USER) corresponds to an input / output device.
That is, the automatically activated AP is a backup program, and seven backup program automatic activation media are prepared corresponding to each day of the week.

First, when a medium in which content to be backed up as a work once a day is written is inserted (Yes in S801), backup is started (S802). At this time, the monitoring utility confirms the media (S803). Here, the header information set in the header area A is taken in (S804). In the header area A, day-of-week data to be executed is set.
The monitoring utility checks the day of the week (S805), and if the backup medium matches the day of the week (Yes in S805), the backup process by the AP is continued (S806). On the other hand, if the backup medium is inserted by mistake (No in S805), a warning is issued to the user and an eject operation of the backup medium is requested (S807). The user who has confirmed the alarm ejects the backup media from the removable media device 10 (S808), and the ejection operation is notified to the media control program as an ejection signal (S809). Receiving this, the media control program detects an eject operation based on the eject signal (S810), and sends an eject notification to the AP via the monitoring utility (S811) (S812). Here, the AP that has received the eject notification can interrupt the backup process on the condition that the backup process has not ended (S813).

  In this way, when an AP is automatically executed, in order to avoid an unexpected situation in which data is destroyed if the wrong AP is executed, the media is detected when an error in media insertion is detected. It becomes possible to respond by ejecting.

As described above, in the present invention, first, the removable media device 10 detects the insertion of the removable media 11 and refers to the header area A of the inserted removable media 11 to automatically start the AP. Recognize that this is a dedicated media. Further, as a response to the inquiry command periodically issued from the host device 20, data such as the AP activation flag, AP name and storage location, AP execution contents set in the header area A is delivered. This realizes automatic execution (activation) of the AP by the higher-level device 20.
As a result, the host device 20 can recognize that the dedicated medium has been inserted simply by issuing an inquiry command, and can automatically execute the AP based on the delivered data. Further, unlike the prior art, it is not necessary to access the contents of the specific area of the removable medium 11 more than necessary. Further, by defining detailed operations in the AP execution contents set in the header area A, it is possible to omit a normal mouse operation and key operation, and thus it is possible to eliminate the need for user intervention in the execution of the AP. .

Further, the above operation can be realized by communication between a media control program (firmware) prepared in the removable media device 10 and a monitoring utility prepared in the host device 20, and the host device 20 sends an inquiry command. It is possible to recognize that the dedicated medium has been inserted simply by issuing it, and the AP can be automatically executed (started up) based on the delivered data, so the burden on the OS can be greatly reduced.
In addition, when the host device 20 receives an ejection notification of the removable media 11 from the removable media device 10 during AP execution, the host device 20 can interrupt the AP being executed, thereby preventing inadvertent overwriting and the like. be able to.

  It should be noted that the media insertion detection unit 101, the dedicated media recognition unit 102, the inquiry command reception unit 103, the inquiry command response unit 100, the flag recognition unit 104 constituting the inquiry command response unit 100, and header information shown in FIG.
